Per my book on Block Codes. C5AE is a 1965 block from a full sized Ford. The E signifies the engineering group which in this case would be the engine group. The A was probably a Galaxie.

As for the crank [crank=c1ae-a] all I can find for that number it says between 61 & 71/390/406/427c.i.d.

As for the heads all I can find in my book which is very limited is a C4AE-F which says they were 64-65/ 427 c.i.d. High Performance Low Riser heads.

I am sure that others with better books will be able to break it down a lot more for you.

I used to have some links to places that had the codes but can't find them.
